I have a software conflict. I bought a new HP Scanjet 4890, and have installed the HP software appropriately. When I open the scanner software program called "HP Solution", my computer monitor goes black for about 4 seconds, and then it lights up again, but all the icons including the HP Solution screen, are in harsh, abnormally vivid colors. When I close that program, there is again a 4 second darkness, and then the screen lights up and is perfectly normal again. While the HP solution screen is open, I can operate the scanner successfully. But I'm scared about whatever it is causing the conflict and instability. I have uninstalled/reinstalled the HP software multi times. Hewlett-Packard support techs say the problem is a Dell issue within my computer.... Dell Dimension 4500 mfg in 2002. Predictably, Dell says it is an HP problem. The computer did, and still does, work fine except for this one issue. I'd be greatly appreciative for suggestions. Thanks
